To prevent external noise from entering the audio system.
• Locate the unit and route the leads at least 10
cm away from the car harness.
• Keep the battery power leads as far away from other leads as possible.
• Connect the ground lead securely to a bare metal spot (remove any paint, dirt or grease if necessary) of the car
chassis.
• If you add an optional noise suppressor, connect it as far away from the unit as possible. Your Alpine dealer carries
various noise suppressors, contact them for further information.
• Your Alpine dealer knows best about noise prevention measures so consult your dealer for further information.
